About Lakenan Lake Dam
The primary purpose of Lakenan Lake Dam is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by James M Lakenan (private). It impounds the Tr-spring Branch near Lithium.
The dam stands 30 feet tall, creates a reservoir covering 8 acres, has a maximum storage capacity of 128 acre-feet, and collects water from a drainage area of 190 square miles. Completed in 1966, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. The most recent inspection on record was 12/19/1980. That was 45 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
